Douglas Fir

DOUGLAS FIR

Pseudotsuga menziesii 

BARK:

Younger bark is smooth and grey-brown. Mature bark is very thick, fluted, ridged, rough, and dark brown.

LEAVES:

Needles are 2-3 cm long, deep yellowish-green, and flat with pointed tips. They are arranged spirally around twigs and have one groove on their upper surfaces and two lines of stomata on their lower surfaces. Buds are sharply pointed.

CONES:

Pollen cones are small, yellow to reddish.

TIPS:

Douglas-fir can be distinguished by the “mice” hiding in their cones. The long, three-pointed bracts look like the hind legs and tail of a mouse. Their thick bark is sometimes described as being corky-like and helps protect them from moderate surface fires.

 

Western Red Cedar

WESTERN RED CEDAR

Thuja plicata

BARK:

Bark is grey to reddish brown, ridged and fissured. It tears off in long strips.

LEAVES:

Leaves are scale-like, glossy, and yellowish-green. They are opposite, overlapping and pressed to the stem in a way that looks like a flattened braid.

CONES:

Pollen cones are minute (tiny), numerous and red.

Seed cones are about 1 cm long, egg-shaped and in loose clusters. Young seed cones are green. Mature green cones become brown, woody and turn upwards.

TIPS:

The branches of Western redcedar trees are J-shaped: they spread or droop and then turn upwards towards the tips. The bases of mature trees are often fluted and buttressed.

 

 

Grand fir

GRAND FIR

Abies grandis

BARK:

The bark is greyish-brown. Younger bark is smooth with resin blisters. The bark of older trees becomes ridged and then scaly.

LEAVES:

Needles are 2-4 cm, dark green and flat with rounded, notched tips. (However, needles on branches with cones may be pointed.) They have a groove on their upper surfaces and two lines of stomata on their lower surfaces. They are usually arranged in two rows spreading horizontally from the branch so the upper and lower sides of the branches can be seen easily.

CONES:

Pollen cones are yellowish.

Seed cones are 5-10 cm long, yellowish-green to green, cylindrical shaped and erect. They are usually found higher up in the tree.

Red Alder

RED ALDER

Alnus rubra

BARK:

Bark is thin, yellowish-brown or grey and often has white patches of lichen on it. Mature bark becomes scaly.

LEAVES:

Leaves are alternate, 5-15 cm long, elliptic with sharp points at the base and tip. They are dull green and smooth on their upper surfaces and rust-coloured and hairy on their lower surfaces. The margins of the leaves are wavy, slightly rolled under and have course, blunt teeth.

FRUITS AND FLOWERS:

Flowers are male and female catkins that appear before the leaves. Male catkins are 5-12 cm long, cylindrical and reddish. Female catkins are 2 cm long and cylindrical. Cones are up to 2 cm long and brownish.

 

Vine Maple

VINE MAPLE

Acer glabrum

LEAVES:

Leaves are opposite, decidous with 7-9 lobes

FLOWERS & FLOWERS:

White or pink in clusters; Winged green fruits that turn brown in fall

ECOLOGY:

Vine Maple usually grows in wet areas of the park or under other trees

Summer Solstice

SUMMERTIME!

Summer solstice has past and summer is officially here!  Even though the days will start to get shorter, we are just beginning to enjoy the warmer weather.

We are looking forward to a busy summer in the park.  Here are a few of the highlights:

  • Partnering with a youth settlement group (South Vancouver Neighbourhood House) to introduce new immigrants and refugees to Canadian wildlife and ecosystems
  • Testing out activities and lessons from our new EcoKITS with Eagles in the Sky (Britannia Community Services)
  • Removing invasives Holly from the Acadia Forest Restoration site with the EcoTEAM
  • Counting aquatic invertebrates (insects) at Spanish Creek with StreamKeepers, Catch the Spirit youth and Nature Kids members
  • Piloting our new EcoWATCH monitoring programs out with volunteers

We hope that you have a chance to explore a new trail in the park or come out to one of our Saturday EcoTEAM events from 1:00-4:00.

Acadia Forest Restoration Project

The PSPS EcoTEAM is launching a new restoration project!

HISTORY: The Acadia Forest has a long history of disruption.  In 1930 and then again in 1951, the Acadia Forest on either side of Chancellor Boulevard was cleared to make way for development.  Thanks to a very dedicated group of citizens, the construction project did not go through and in 1989, much of the UBC Endowment lands became a regional park.

PROBLEM #1: Deciduous trees, including Black Cottonwood, Red Alder and Big-leaf Maple quickly established in the cleared site following the clearing.  However, the conifer seed source was removed during clearing, creating an unnatural growth pattern in the area.  Deciduous trees usually start to die after 60-80 years, just as the conifer trees start to take over.  With only a hand full of conifers, the Acadia Forest is missing the next generation of trees!

PROBLEM #2: Disturbed sites often are perfect areas of invasive plants to spread quickly and the Acadia Forest is no exception.  The area is covered with invasive English Holly, as well as Himalayan Blackberry, English Ivy and English Laurel.

RESTORATION: Over the summer the PSPS EcoTEAM will be removing the invasive plants.  Then, to encourage the natural forest succession and to outcompete the invasive plants as they return, we will be planting conifer trees and shrubs in fall.

SUPPORT:  This project would not be possible without the support of:

  • Pacific Parklands Foundation
  • Metro Vancouver Regional Parks
  • Vancouver Park Board

Spring Songs

North Country 

In the north country now it is spring and there

is a certain celebration. The thrush

has come home. He is shy and likes the

evening best, also the hour just before

morning; in that blue and gritty light he

climbs to his branch, or smoothly

sails there.  It is okay to know only

one song if it is this one. Hear it

rise and fall; the very elements of your soul

shiver nicely.  What would spring be

without it?  Mostly frogs.  But don’t worry, he

arrives, year after year, humble and obedient

and gorgeous.  You listen and you know

you could live a better life than you do, be

softer, kinder.  And maybe this year you will

be able to do it.  Hear how his voice

rises and falls.  There is now way to be

sufficiently grateful for the gifts we are

given, though do try, and

especially now, as that dapples breast

breathes in the pines and heaven’s

windows in the north country, now spring has come,

are open wide.

What songs are you hearing in the Park these days?
